Its primary features are: - convenient PHP wrapper around the API calls and responses: - marshalls PHP request objects to HTTP requests - unmarshalls HTTP responses to PHP response objects or PHP exceptions - handling of all the details concerning authentication - handling of required metadata See the [Online Payments Developer Hub](https://docs.direct.worldline-solutions.com/documentation/sdk/server/php/) for more information on how to use the SDK. Structure of this repository ---------------------------- [](#structure-of-this-repository) This repository consists out of the following components: 1. The source code of the SDK itself: `/src` and `/lib` 2. The source code of the unit and integration tests: `/tests` Requirements ------------ [](#requirements) PHP 7.4 or above is required. In addition, to support streaming uploads, package [robtimus/multipart](https://packagist.org/packages/robtimus/multipart) is required. Installation via Composer ------------------------- [](#installation-via-composer) 1. Initialize [Composer](https://getcomposer.org/download/) in your project, if this is not already done, by executing the following command: ``` composer init ``` 2. Add a requirement to the SDK to your `composer.json` file by executing the following command: ``` composer require online-payments/sdk-php ``` 3. Add `vendor/autoload.php` to your project, if this is not already done, by adding the following line of code: ``` require __DIR__ . '/vendor/autoload.php'; ``` Manual installation ------------------- [](#manual-installation) 1. Download the latest version of the PHP SDK from GitHub. Choose the `sdk-php-x.y.z.tar.gz` file from the [releases](https://github.com/Online-Payments/sdk-php/releases) page, where `x.y.z` is the version number. 2. Add the contents of the `tar.gz` file to your project. The content of the `/src` and `/lib` folders may be combined, if this is required by the project. 3. Add all classes from the `/src` and `/lib` folders to your autoloader; all classes inside these folders are compliant with [PSR-4](http://www.php-fig.org/psr/psr-4/). Development and testing ----------------------- [](#development-and-testing) 1. Install [Composer](https://getcomposer.org/download/) 2. From the root of the sdk-php project, run `composer install` 3. Copy `tests/config.json.dist` to `tests/config.json` and replace the template values by actual values 4. From the root of the sdk-php project, `vendor/phpunit/phpunit/phpunit` (or just `phpunit` when it is already installed on your local machine) ### Health Score 54 — FairBetter than 97% of packages Maintenance89 Actively maintained with recent releases Popularity37 Limited adoption so far Community14 Small or concentrated contributor base Maturity62 Established project with proven stability Bus Factor1 Top contributor holds 100% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
